本文的主题是关于印度尼西亚在达到中等收入水平时,经济、政治和社会方面将面临的挑战。这是一个有趣的议题,但也是一个涉及面很广泛的议题。因此,本文把主要的讨论点缩小到经济和社会方面的问题。在把本文主要局限在讨论经济问题时,笔者使用的是比较利益这一个强有力的经济法则,从而使我们大家都能从中受益。 The topic of this paper is about the economic, political and social challenges that Indonesia faces when it reaches middle-income levels. This is an interesting topic, but it is also a very broad issue. Therefore, this article narrows the main discussion to economic and social issues. In confining the paper primarily to economic issues, the author uses a powerful economic law that compares interests so that all of us can benefit from it.
